Where does Apache get its search path

as0k has asked for the wisdom of the Perl Monks concerning the following question:

Note:This is sort of a continuation of an earlier question I had this node Problems with environment variables.

Alright I was using CPAN. It upgraded my version of perl from 5.6.0 to 5.6.1, but instead of upgrading the old vers. of perl(/usr/bin/perl) it installed itself in /usr/local/bin. All the pm's I download are now installed under the /usr/local. Now when I went to start apache it died, because it couldn't find the PM's it needed under the paths for the old/default version of perl. So, I renamed my old perl binary, and created a symbolic link to the new one, since the new binary(5.6.1) had the correct path information (I've checked it to be sure).

I now try to start apache again, and I get the EXACT same error message with the EXACT same search paths as the 5.6.0 version of perl, instead of the new 5.6.1 paths.

Not to be outdone, I then tried to modify my environment variables, with 'export PERL5LIB='and supplying it the appropriate paths. Then I try start apache. I get the same error message, EXCEPT this time it has the 5.6.0 AND the 5.6.1 paths listed. That means it has the correct paths (yes I check SEVERAL times for typos) AND the old ones, but for some reason it still can't find the PM's. I'm really perplexed on this one. Please help.

The default include path is compiled into Apache. I don't know if this is the 'proper' way to do it (my mod_perl book is at the office and I'm not), but this does work. `<perl> BEGIN { push(@INC,"/home/maverick/"); } </perl>` [download] Adding something like this to your httpd.conf or perl.conf file will cause @INC (the include path array) to be modified at server start time BEFORE it tries to do any PerlModule, require or use directives. /\/\averick perl -l -e "eval pack('h*','072796e6470272f2c5f2c5166756279636b672');"	[reply] [d/l]

I assume you're talking about mod_perl, since it's easy to change which perl a CGI script is pointed at. With mod_perl, you need to recompile it when you upgrade Perl. It is linked to Perl at a deeper level than just a path, and no amount of @INC magic will fix it.	[reply]
